||x-2|-6|=4

x+13x+1

Answer 1

||x-2|-6|=4

|x-2|-6 = 4                              lub        |x-2|-6 = - 4

|x - 2| = 10                             lub          |x - 2| = 2

x - 2 = 10   lub  x - 2 = -10        lub           x - 2 = 2         lub x - 2 = -2

x = 12        lub      x = -8          lub              x = 4            lub   x = 0

 

 

 

x+1 ≤ 3x+1

x - 3x ≤ 1 - 1

-2x ≤ 0    /:(-2)

x ≥ 0

x ∈ <0, +oo)
